From September 2015 to January 2019, we initially enrolled 13,160 pregnant women aged 18 to 50 years who received antenatal care in Foshan city, Southern China. Questionnaires for collecting basic maternal information were completed at their first hospital visit for pregnancy. In addition to the questionnaires, participants were asked to complete the entire prenatal examination at a fixed hospital. All the participants were followed until delivery. Clinical measurements and neonatal information of newborns were collected from the hospital's electronic medical records management system, which was recorded by gynecologists. We included pregnant women who had their blood cell count measured at least once during pregnancy.

修改部分：

1. 去掉句子中的多余单词“was”。
2. 将“finish”改为“complete”。
3. 将“information”改为“neonatal information”以更明确表达信息类型。
4. 增加“had their blood cell count measured”以使句子更加完整。
